Abstract
A system and method for controlling communications in a security system based upon RFID techniques. The RFID reader of the security system can be provided with multiple modulation techniques, multiple antennas, and the capability to vary its power level and carrier frequency. The controller of the security system determines which RFID readers may transmit, at what times, and the parameters with which to transmit. The RFID transponders of the security system limit their transmissions to responses only, and only when information to transmit exists. The controller may vary the parameters used by the RFID reader based upon the RFID transponder that is being addressed. The RFID reader can detect interference or jamming, and respond.
